Thank you! I purchased the dsmlink used and I thought I had set everything back to stock.. makes perfect sense lol. When I get more into tuning it I will included more details about the build including the stuff you mentioned.

Is the plastic popping out of the coupler?

My wideband is close but not accurate, I have a innovate coming in the mail tomorrow. I started messing with the timing a little bit, I had like 10 degrees of knock on the first pull but the erratic afr readings were throwing me off. I’m starting to think it’s the maf.

Is your hard pipe coupled to a plastic pipe?

What's causing this erratic behavior in the afr readings? Wiring? MAF?

Thanks for your inputs, I went ahead with the kynar one from us plastics.

Anyone have a link to a check valve they use in between their IM and pcv? Or a pcv valve that doesn’t leak...

All that was done about 20k miles ago I have all the tools besides the special tools. I know how it’s done, I just have to get the balls to do it, let alone the time.

Agreed

Yea Florida is a sweat shop basically.

fort Myers is a bit far from me I think like 2 hour drive

I was out of the loop for a few years lol

I thought so hahaha

Figured it out the diagnostic plug wiring was messed up somewhere in the harness.
